    After I shut the engine off there is a "chirping" or "eeep" sound coming from what looks to be the VSV (EVAP) box on the right side of engine bay, upper portion. Its the black box with all the vacuum lines going to it... If I disconnect one of the fatter vacuum lines, the noise stops until I reconnect it again. It will emit this noise for about 15 minutes after engine shutoff. Anyone else have this happen? Is this normal?

    the flange inside the valve may be going bad and leaking . . . causing it to make a high pitch squeel

    yeah...the aftermarket has a lot to offer. I prefer the oem stuff though.. so a junkyard would be a good place to look.

    lol yeah when will (tacomaman06) and jeff (tigerfan00) were working on my truck it was doing it... they were like wtf is that. I said dont worry my truck just ate and now it has gas lol i wouldnt worry about it dude

    oh and dont take it to the dealer to find out what it is cause they will try to charge an arm and a leg to find out what it is and then say they dont know what it is (happened to my dad)
